Unable to get video back GT2.0


My gt 2.0 has been working fine till last weekend tried to watch a movie. The screen went back and white. So I checked all cables and replace new cables. Still getting b/w. Stupid me shouldn't have mess with video settings in gt 2.0 changed it from s-video to rca and now I can't get any video from any port. I have already did factory reset 5 times and no video still. Have googled and found out I will need a bin file to upload. I found a post here https://heartlandowners.org/showthread.php/30585-SOLVED-No-video-on-GT-2-0 . So I have contacted Concertone for a week and cant get any respond. Does anyone have a bin file for this gt 2.0?
